TIRE TOOL.

Application flied I'ebruary an, 19 2. Serial Ho. 537,900.

of adjusting the tool' to. different sized To all whomz't mag concern:

Be it known that I, Winnie W. Hrnnm, a citizen; of the United States, remdin at 'Jonesboro, in the county of Union and tate of Illinois, have invented certain new and useful Improvements'in Tire Tools; and I do hereby declare the following to be a full,

clear, and exact 'description'of the invention, such as will enab e others skilled in the art to which it-appertainsto make and use the same.

This invention has for its ob'ee t the provision of means whereby to acihtate the dismounting of pneumatic tires from split rims which are contracted to admit of the easy removal of the tire therefrom for any re ired purpose.

he invention aims to rovide a tool of the character aforesaid w 'ch is efiicient 111 service, adapted to be readily manipulated, adjustable within certain limits to diflerent sized rims and capable of being folded into compact form so as to be readily carried as an adjunct to a kit of tools for auto mobiles and motor vehicles generally.

Other objects and advantages will be apparent and suggest themselves as the nature of the inventlon is understood.

While the drawings illustrate an embodiment of the invention it is to he understood that in adapting the same to meet dilferent conditions and requirements, various chan s in the form, proportion and minor detai of construction may be resorted to without departing from the nature of the invention Referring to the accompanying drawings forming a part of the application,

Figure 1 is an elevation showing the application of the tool,

Figure 2 is a detail view in perspective of thetool, and

Figure 3 is a view showing the tool folded for convenience of handling and storing so as to be conveniently carried as an accesso to a tool kit.

arresponding and like parts are referred description and designated in the sever views of the drawings by like reference characters.

The tool comprises an operating lever l which is provided at one end with a head 2. Arms 8, 4 and 5 are pivoted at their inner ends to the head 2, one of the arms, as 5, being adjustable as to length to admit rims within certain limits. Each ofthe arms is providedvat its router and with a hook 6 to positively engage the rim 7. The arm 5 has an ad ustable section 8 which is formed along an edge with a plurality of teeth!) which are adapted to cooperate with a pin 10 or like part to hold the section B in the required adjusted position. A'longitudinal slot 11, formed in the section-8, receives a pin 12 of the arm 6, whereby to retain the section in position and prevent displacement thereof. A toothed bar 13 is pivoted at one end to the lever 1 and is adapted to cooperate with a pin 14 or like part carried by the arm 4:, whereby to hold the part in the required adjusted position as indicated most clearly in Fi re 1. When the tool is not required or immediate service it may be folded into compact form, as illustrated in Figure 3, whereby it may be conveniently carried as an accessory of a tool kit. o

In operation, the arms of the tool are extended and the hooks 6 thereof engage over the outer side of the rim 7 to be contracted, the arms when extended being approximately equidistant. After the tool as been adjusted to the rim 7, the lever 1 is rotated in the plane of the rim thereby drawing the arms inward and contractin the mm, as illustrated in Fignregl w erehy the tire 15 may be readily remov therefrom or laced in position thereon. The rim is hel contracted by engaging the toothed bar 13 with the pin or stop 14.

In order to revent the tooth bar 13 from moving laterally oif of the pin or stop 14, a guard 16 is employed. This ard 15 secured as at 17 to the arm 4 an -itis provided with an off set portion 18 through which the pin or stop 14 passes and which engages the outer side of the toothed bar 13 when the latter is in engagement with the in or stop 14.

at is claimed is:

1. A tire tool of the character specified comprising an operating lever, arms pivoted at their inner. ends to an end portion of the operating lever at different points and having rim engaging elements at their outer ends, one of said arms bein of sectional formation, the outer section having a longitudinal slot and a plurality of teeth along an edge, a pin carried by the inner pivoting the outer section to the inner secodop'erat-ing means' between the operating -%ue =bf-zwhich s ecured eoeaichsfde'bf ithe im mben. which'is sedui'ed. p0 .bhehead', the enter *set ian ofl's'eid' arin positioned between "means associated wit "ihelbai's.."ihefitidi1ed "efid hiiriiiigih' itudinal slot through which a. pin cerrie' by said hars ges ses, aid outer seating; hajrjp "a fseri'eefliflfieefih gjloi'l'g'hiie' ed'g', fi-ii hth adfiptecl- 110' b'eelectively engaged with a econd pin carriedby said bars and which 'is "spaced from the ends thereof, the outer .end sai e uts 9 being 'PmYidedwith a rim enga'g'uig element, a bar pivoted to the dpemting lever apd; :h@Yiqgga;;fse1fies of .teet-h "'ak'rhg, one edge-fadaptegil to; egge 'e .*a pin eerried by' anezadjecent egn; ed *the parias ifljdct-iveg qsitiqg aln gi'ea ism-peace. -saii.d;;bar' mbiringflatetellyofithe pi a lntb es't'rmony whelfeqf' ;I afiix my m'- reserlicebf -t -w'mfvy-i;i; n ess es e .WILLIS H EM N. witnessesrmqs e v C.
